What can you do with polystyrene?
Polystyrene can be used in various industries like Polystyrene Packaging, Construction, Display, Exhibition, Signs, and all areas of the foam industry. Various different items can be produced from polystyrene. For a complete range and details about products please visit: http://www.polystyrene.uk.com/
Is styrofoam the same as polystyrene?
They are made from the same polymer, polystyrene. Usually polystyrene is clear, hard and rigid, for example in CD cases. However, styrofoam is created by blowing air through liquid polystyrene. The bubbles are locked in the polystyrene as it solidifies, giving the syrofoam used in packaging and cups. The reason it is compressible is because the air is compressed, rather than the hard, rigid polystyrene itself.
What metal is used as a container for food stuff?
Your best bet for avoiding rust would be to use stainless steel containers. If that's not an option, look into anti-rust coatings for your containers. There should be a way to prevent oxygen from hitting the metal and causing the oxidation that is rust.
The name of the plastic polymer from which combs toys bowls are made is?
Polystyrene plastic Polymer is used to make combs.
Why is polystyrene brittle?
Unfilled polystyrene is also known as crystal polystyrene (PS) or general purpose polystyrene (GPPS). However, since crystal polystyrene is brittle, other polymers are added to polystyrene to improve its strength, and copolymers are formed as a result. One such copolymer is high impact polystyrene (HIPS), which is produced by adding polybutadiene rubber to polystyrene during the polymerization process. HIPS is tougher and has a greater impact strength than unfilled polystyrene. There are different types of polystyrene. Extruded polystyrene (XPS) is one form of the polymer that has high tensile strength, with good elasticity. It is commonly known as Styrofoam™. The other common form of polystyrene is expanded polystyrene (EPS). Both EPS and XPS are made from similar materials but there are difference between the two. XPS has a higher density as compared to EPS, due to the absence of air passages between its cells. The higher density makes XPS more rigid and strong. Also, XPS is waterproof and is an effective thermal insulator. Read more in the related link.

Are Polyethylene and polypropylene made from crude oil?
NO. See Link. YES! From http://www.sustainablebusiness.com/index.cfm/go/news.feature/id/1363 Traditional foam "to-go" containers are made of polystyrene, while the clear plastic containers and bottles we see everywhere are made of polyethylene terephthalate (PET), polystyrene or polypropylene -- all petroleum-based plastic polymers. The ubiquitous paper coffee cup, and the paper take-out containers we see everywhere, also use a petroleum-based plastic coating to make them waterproof. According to Green Seal, in 1997, 120 million pounds of foam polystyrene hinged containers were used in the U.S. food packaging industry and each American throws away an average of 100 polystyrene cups each year. Green Mountain Coffee Roasters recently estimated that last year Americans used 14.4 billion hot paper cups (placed end-to-end, this many cups would circle the world 55 times). Not only do these plastic cups and take-out containers create garbage that ends up in the landfill for centuries to come (a polystyrene cup has an expected lifetime of over 500 years), they are made from non-renewable petrochemicals, and styrene, a key ingredient of polystyrene, is a suspected carcinogen and known hazardous substance.
Is super glue safe on food containers?
It is safe when dried,- but it may not work on many food containers, especially those made with polyethylene.
Are Rubbermaid food storage containers made with safe plastic?

What type of plastic are kitchen utensils made from?
- Polystyrene (PS) - Used in Styrofoam containers, egg cartons, disposable cups and bowls, take-out food containers, plastic cutlery, compact disc cases. Leaches styrene, which is an endocrine disruptor mimicking the female hormone estrogen, and thus has the potential to cause reproductive and developmental problems; long-term exposure by workers has shown brain and nervous system effects; adverse effects on red blood cells, liver, kidneys and stomach in animal studies. Also present in secondhand cigarette smoke, off-gassing of building materials, car exhaust and possibly drinking water. Styrene migrates significantly from polystyrene containers into the container's contents when oily foods are heated in such containers
